Linker issues migrating from v6 to v8

[Tomas_T_]

I'm currently trying to test Ipp 8.0 on a Linux platform (Ubuntu 12.04) where I've been using version 6.0.1

I'm trying to link statically but I always get: 'unresolvable R_386_GOTOFF relocation against symbol `ippJumpIndexForMergedLibs' which prompted me to try the nonpic libraries. 

This worked well enough for one simple application but another, more complex ones fails linking with a host of errors similar to this (full list attached):

/opt/intel/composer_xe_2013_sp1.0.061/ipp/lib/ia32/nonpic/libippi.a(piresset_p8---ownResize16plLz3.o): In function `p8_ownResize16plLz3':

Help on identifying the issues would be much appreciated 

linker command g++ -o build-host-debug/bin/xrp -L/opt/intel/composer_xe_2013_sp1.0.061/ipp/lib/ia32/nonpic -Xlinker --copy-dt-needed-entries -L./build-host-debug/lib -Wl,-rpath  .... long list of .o files and libs

[Tomas_T_]

Changed line 39 using two sets of single brackets instead of the double so now it runs. Still get the same error when linking.

Can you suggest further tests?

[Pavel_B_Intel1]

Please check how do you place IPP libraries in link string. You should keep dependances in IPP libraries, for example if you use functions from Image Processing (ippIP) library you should point:

$IPPROOT/lib/ia32/libippi.a $IPPROOT/lib/ia32/libipps.a $IPPROOT/lib/ia32/libippcore.a 

because ippIP depends on ippSP and ippSP depends on ippCore. The full list of dependances you can see in IPP User Guide.

[Tomas_T_]

Thanks, still the same though.

I think I'll just evaluate using nonpic libraries 

[Pavel_B_Intel1]

Please check if you point IPP libraries in correct order. Could you provide link string (how do you point IPP libraries)

[Tomas_T_]

Ok - found a really stupid error on my part. I was linking to components linked to the old version of IPP.

Removed that but that brought me a different set of errors

Also it seems like the environment vars set by the ippvars.sh script do not stay in my system

[Sergey_K_Intel]

These functions are from Intel compiler's libs, probably from libirc. Try to add "-lirc" to the end of g++ command line. "icc" does this automatically, while "g++" requires explicit library reference.

[Tomas_T_]

Thanks - that did the trick.

Am I meant to run the ippvars script each time I want to work on my IPP projects?

[Pavel_B_Intel1]

ippvars.sh script setup  IPPROOT and LD_LIBRARY_PATH environment to simplify work with IPP libraries. You can setup this variables in your profile file and no necessary to run ippvars.sh each time in this case.

I noticed that Tomas T used "lappbase" on the #26. In my project, the compiler such an error: /usr/bin/ld: cannot find -lappbase. I do not know which library "lappbase" comes from, so I do not know how to solve it. I hope someone can explain it. My system is RHEL5.5. Thank you very much! My e-mail is yi445250544@gamil.com
